A journal In Fig. '1 I have not shown the adjusting or pin 0projects from the outer end of the lo parts in that part thereof whichrelates to the part K near the periphery thereof, as shown 50 plumb.best atFigs. 7and 8. Ashort screw 1) (which Referring to the drawings byletters, A repis fir'st passed through the part B of the resents thelevel-stock, which is preferably of frame B) is threaded into andprojects from the outer end of the part K of the cylinder near theperiphery thereof. The tube J is firmly fixed in the part K, and thepart or extension K is then telescoped into said part K, into which itfits snugly, thereby maintaining the parts in the desired relation toeach other-that is, the parts 0 and b in a longitudinal line with eachvother and with the bulb or sight J in the level-tube J.

Should the level-tube become broken or should it for any reason becomedesirable or necessary to insert another tube, it may be readily andeasily accomplished as follows: The screw F being withdrawn from theboss D and one of the cap-plates H removed, the frame B and itscontained parts is lifted out of the stock A. The part K is thenwithdrawn from the longer part K of the cylinder K, the old or brokentube removed from said part K and a new one fixed therein in properposition, and the part or section K again telescoped into the part orsection K.

The parts are assembled as follows: The level-tube J being properly andrigidly fixed in place in the cylinder K, the pin 0' and the screw I)being in a longitudinal line with each other and with the bulb in thetube, said pin 0 is inserted in the opening 0 in the plate 0, whichplate is in its place in the slots B in the extended end B of the frameB. The screw b is then inserted or passed loosely through the opening inthe extended end B of the frame B and is threaded into the screwthreadedopening in the end of the part K of the cylinder K, thereby securing theleveltube and the cylinder K in proper position within the frame. Saidparts are then placed in position in ahole or opening extending throughthe level-stock and the cap-plates fastened in place, as shown best atFig. 1. The screw E is then threaded into or through the boss D througha mortise L in the levelstock.

Adjustment of the level-tube and cylinder is effected as follows: Thehead F of the screw E resting, as it does, against the shoul der G inthe mortise L in the level-stock and being threaded into the boss D onthe adjustable plate O, when said screw is turned to farther enter saidboss it will raise said plate, and thereby the adjacent end of thecylinder and level-tube. When the screw is turned in the oppositedirection, the result or effect will be the reverse. The screw-plugG isused only to gain or prevent access to the head F of the screw E and toprevent displacement thereof. The pin 0 and screw I) being looselyjournaled in the openings or journal-boxes cand I) allow the cylinderand level-tube to swing freely therein. Said cylinder and tube beingsuspended from journals located near the peripheral edges of its endsand said journals being in a longitudinal line with each other and withthe bulb in the level-tube, the diametrically opposite side of thecylinder will descend by gravity, and in whatever position the level isplaced the bulb will always remain uppermost.

When the device is used as both a level and plumb, the parts are locatedthe level about the central longitudinal part of the stock and the plumbabout onethird the distance from the end of the stock to its medianpart. When it is desired to use it for battering, (the plumb only beingthen used,) any desired inclination may be secured by adjustment of thescrew E. (Not shown in that part of Fig. 1 relating to the plumb, butcorresponding to said screw elsewhere shown in the drawings.)

I do not wish to be understood as limiting my claims to the exact mannerof mounting the cylinder in the frame B at the end B thereof, as it maybe done in any desired or preferred manner. I have accomplished it asfollows: A pin 5 similar to the pin 0', is fixed to the cylinder, asshown at Fig. 8. This pin is loosely journaledin a bearing in the innerend of a set-screw which is threaded into and through the end B of theframe B, thereby effecting a similar result. When it is desired toremove the cylinder from the frame B, it may be readily and easily doneby simply loosening the screw, thereby releasing the pin and cylinder.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a spirit-level, and in combination, a stock, a cylinder containinga level-tube, an adjustable plate in' which one end of said cylinder isjournaled, the other end of which cylinder is journaled in a bearing ina frame, and an adjusting-screw for raising and lowering said plate and.thereby one end of the level-tube, substantially as described and shown.

2. In a spirit-level, and in combination, a cylinder containing alevel-tube, an adjustable plate in which one end of said cylinder isjournaled, the other end of which cylinder is journaled in a bearing ina frame inclosing said parts, and said frame inclosed in a level-stock,and means for raising and lowering said plate and thereby the adjacentend of the cylinder, substantially as shown and described.

3. In combination in a spirit-level,the levelstock A, the frame B, thecylinder K, the sliding adjustable plate 0 and the screw E, allsubstantially as shown and for the purpose described.
